SMA Solar Technology AG Operation
Technical Description SI5048-TEN093630 77
Request reason "Cycle":
The generator was requested via the generator operation's time-dependent
repetition cycle.
Requirement reason "Load":
The generator has been requested as a result of the load-dependent generator
request.
Requirement reason "Start":
The generator has been requested by the operator manually setting the generator
request in the Sunny Island from "Auto" to "Start". The generator is then no longer
automatically controlled or switched off by the Sunny Island.
Requirement reason "Time":
The generator was started for one hour using the "Run1h" setting in the
Sunny Island. Once this time has passed, the Sunny Island automatically switches
off the generator.
Display for relays (solid circle = the relay is activated / empty circle = the relay is
deactivated).
Warning message:
This symbol blinks until you have viewed the warning in the menu
"410# Failures Current" or "420# Failure History".
Display "Generator Status" and "Request Reason"
Both indications mentioned above appear alternatively on the display as status of the
external source.
Example:
If, for example, the display changes every 3 seconds from "*" to "B", this means that the
generator voltage and frequency lie within the specified limits and that the generator was
requested as a result of the battery charge level.
Stopping the Generator Manually
If the generator has been manually set to "Stop", then no generator status information is
shown on the display. The field remains empty in this case.
Indications of a Warning
If faults occur, the device switches into standby mode and shows the fault on the display.
The fault must be eliminated and confirmed, then the Sunny Island carries out an autostart.
